Bring a domain you control
Start with a low-risk custom domain rather than a business-critical mailbox.
Early access for design partners
Help shape what reaches the inbox.
TrustSender is inviting a small group of people to test a working prototype with one low-risk custom domain. You will help define communication policies, review decisions, and improve the explanations behind them.

What participation involves.
Review every decision
